Abstract:Oceanic internal solitary waves are widely distributed within the stratified layers of seawater, playing a crucial role in the transfer of material energy and oceanic circulation. They also have an important impact on ocean engineering construction and ship navigation safety. Machine learning technology utilizes data to train models, enabling computers to possess the capability of learning and improving performance, and is widely used in areas such as image detection, segmentation and prediction. This paper discusses the application of machine learning in internal solitary detection and recognition, parameter inversion and propagation prediction, and points out current research issues, such as insufficient research on internal solitary wave datasets and specialized algorithm. Finally, the future development trend of machine learning in internal solitary waves is analyzed.
